Ee it known that I, MAURICE F. GEER, eicitizen the United States, and resident of the city of Rochester, in thecounty 'ot' Monroe and State of -Nev York, have in- 'ventedn new and useful Time-Announcing System, which the following is a speci- 'itionQ j Y "lnsinveuton e'lates to a time announcand particularly to a. system of announcing time applicable toa selective fr" e stein.

-mary object lot this invention is to ct and arrange. a system of circuits and devices 1wherebytime may be announced' at all of the stations comprised in a selecsignalmg system, oy employing just as much of l. tire signaling apparatus as is possible, and Without interfering in any manner with the normal selective operation oit tile sy For a great many years the movements of trains upon rsilways have been facilitated lof: the use of the telegraph. The ordinary method is to here a so called despatcher at central point, 'who ltransmits orders by :apli to locals'tations concerning the delis connected, so that each local operator may adjust liis clcclt daily.

llf'lien tlie telephone is used for controlf VVements, it is necessary to also stem tor. selectively calling the ,ole .to, announce. time by sucliselec- `sisralifog: pointed out it ye of the objects of applicentis ,intention-tol acconjiplic" sugli act.

At the despatcliers station are located calling keys, indiifidual to each local station, which, when manually operated, cause, in the embodiment shown, a bell to be rung at the particular local station `With which the despatcher desires to communicate. The individual keys are constructed., arranged'and connected as fully set forth in the fro-pending joint application F. Greer and Richard C. Leake,-Serial No Getest, sied May 10th, 1911.

It should be noticed that the current flowedv out on line wire 2 and returned on line wire 1, and

five positive impulses will -be sent to line wire 2 and-by the time the last tooth has. passed spring" 11, the first tooth 'on'wheel 4 will be in position to con-tact` tosl ring 12, so that current will flow in the, ollowing path; -positive terminal of battery 20wires 45,46, 47, 48, 49, 50, 51, si, 52 and 77, shaft a, tooth of wheel 4, spring 12 and wires v'78, 79, 80 and 81, coil 35 on line relay 34 and wires 72, 58 and 59 to the negative terminal of bat-` tery 20.

As the Wheel el has 6 teeth on its periphery, there Will bef 6 positive impulses sent to line Wire 1. Applicants systern of selectors 1s such kthat although any impulse of electricity sent to the line causes all of the selectors at the.

different stations, to operate, the one only 'Which will cause its associated indicator toV operate is the one adjusted to be set in a certain definite position by the particular combination of impulses' sent to the line. After the Wheels 3 and l have caused irnpulses of one polarity'and six of an opposite polarity to iow to the line, the selector at station B will be so positioned that another impulse flowing to the line in the same direction as the impulses caused by the malte and break by the tooth on Wheel 3, Will cause the selector to-so operate as to cause the` indicator associated therewith to rlhis impulse Will he obtained. by

the proJection on the Wheel 8i contactingv With spring 83 so that a circuit is formed in which current flows .as follows; ininal of battery E20, 50, 51, 8l, 52, 85, 86, shaft s, projection on Wheel 82, and 70, coil 36 on line relay 34 and Wires il, 72, 58 land. 59 to the negative terminal of battery Q0. Current in the above traced path causes the right hand end o armature 37 to beraised and causes current to i'iow from generator 22 in the saine direction that it flowed when the teeth on Wheel 3 made contact'with spring 1.1, that is to say, it flows to line Wire 2. The last described iur pulse is of longer duration than those caused by the teeth on Wheels 3 and l as the projection upon Wheel 82 remains continuously in Contact kWith spring V83 for some time. This last mentioned impulse causes the selector at station B to complete its movement,

close a Contact and cause an indicator attire .stationto be operated, in will h'ereater bedescribed.

W'heels 6 and 7, together with sector 8 ana Wheel 89 operate in exactlyl the saine inana manner `which 82. operate, the only ;flill'eience being that Wheel-6 has 3 teeth, Whereas Wheel .3 has 5, and iii-heel 7 has 4: teeth, Whereas, Wheel has 6. 'The result of this change is that-'3 iinpulses are sent to the lin-,e by operation of Wheel G and by the operation oli Wheel?4 andthat particular combination or impulses operates selectively upon the selector at station'C, so as to place it in such positionv that spring .83, Wires S7, 6T, 68, 88, G9

' has such a' number of teeth and torce it a further impulse, caused by `Wheel 89 will cause a` contact at the selector to rhe closed andthe indicator to he' operated.

,The selector.- the local stations. such as Band C,fis of af type fully shown, `descriloed rvand claimed inf the joint applicatipnmot Maurice l?. Geer and 4Richard C. Leuke, kSerial No. 596,252, filed'December 8th, 1910, therefore it will' suilice in this case to merely point out the general' features. 92and 93 designate Jott iron cores upon which coils 94 anda-,5 are Wound, the coils being connected together and Wires 1 and Q. There 1s provided a polarized armature 96, oscillatable upon a knife edge pivot 07, there being an arm 9S attached to the armature 96 which carries at its upper enc. two driving p'an'ls 100 and 101. yDriving pawl 100, when moved to the left, contacts `with and causes sector 102 to rotate in multiple with line i about a central pivot and at the same time Y vtion by reason of spring- 141 when the impulse of electricity ceases. Successive impulses advance sector 102 step by step' and it is held in its successive positions by holding ,oasvl 1&3. When the :win98 is moi-'ed to the right, paul 101 actuates the sector 107 to causeI it to rotate about a central pivot and thepaivl 1,08 released from engagement With the tail end 109 v movement of vsector 102 falls .into engageinen't with the teeth of sector lOZand holds it lin the moved position. The sector 107 in its periphery" that 18 impulses of such polarity as to more' arni 9S to the right, causes the last tooth 110 to engage With thepawl l108 so that although drivihg paul 101. may iontinue` to recipro cate, the sector 107 will return after each acof sectorv 10:2 by the previous tuation so that thelasttooth 11,0"rests in Contact With holding-pawl 10S;f VVheu the sector 107 has' beenso moved v:hat holding pawl 108 Vrests against thelas'tfurther iinpulsewill cause'the progection lll on sectorl` to engage ufithfspringl-l?, into Contact with spring 113.

lf 5 impulses are sent through coils V9st and 05 of the selector at station yi3 in such a direction as to cause the right hand end of' armature 96 to be drawn upwardly 5 times then the sector 102ivill be advanced 5 teeth and as erin 114 is rigidly connected with sector 10:2,.it 'Will hemoved to,y a vertical position, lien if sector '107' is advancedf steps .hyl reason of Wheel 1l, then arni 115 which is attached thereto, -will. be moved to ay vertical position directly in line withV arm 11e, then itam impulse is sent tothe line by .means of wheel 82 and spring 83, the

tooth* 110,

right -handend'i'of armature 96 will 'again tie-drawn` upwardly, the-driving pawl 100 moved to the left and by reason of the fact that .the-'tail 'end 11.6 of sector 107 has been moved 'downwardly by the actuation of 'sector 107, the driving pawl 100 will engage l member 11'7 and rotate it on pivot`118 vtherei by causing plunger 119 'ded' by arm 114 I. to', contact with outstan ing arm 120 and .cause the .member 121 topress against spring 122 and cause it .to move into contact with spring 1 23, so that the current flowing along line wire v2 may pass' by means of .'Wires 124, l1251. and ,126 through coil 127 to mer 135 -to strike gong 136 and would at the.

sannetii'ne break 4contact between wire 128 and contact 129 and at the saine time make contact between wire`137 and contact 138 so .'that'the current'which iiowed from-wire 125 .to wire^126 would then tlow through coil 139 to-wire r137 and contact 138 to armature 130 'and then'to wire 131 as'before so' that the armature138 would be drawn upon the left causing hammer 135 to strike gong 140 so that a'continuous ,ringing would j'ke place as long as springs 122 and 123 were connected, springs 122 and 123..woi ild be coniiected as long as the projection o n wheel 82 was. in contact with spring 83, but as lsoonas contact was broken at that point thearmature 96.wo`u`ld return to its normal 'position by reason of spring. 141, thereby causing arni 498 and pawl 10() to return to the initial position thereby releasing 4arm 117 4which would return it to its initial position cessation of current The selector and bell shown at local stay tion C, Fig.

All of the-parts heretofore described have in the two applications heretofore.. tioned, and it now remains to descrA av movement of manner in which applicant is able bythe use of the same selective calling apparatus to transmit an announcement of time to eachl and every local. stationsimultaneously.

Relay 146 is connected to what yis called .the illestein Union ctime circuit, so 'that when that circuit is closed, armature '147 is raised. That circuit is closed beginning exactly two minutes before11 oclo'ck a. in., and 1s so arranged that it is closed for an then again opensand vso on until exactly fifteen seconds before 11 oclock, when' it is opened and held opened until exactly'f y11v A oclock, at which time itis closed.; thus indieating l1 oclock exactly. 'It is thenl opened and closed every second until two` minutes after 11 ocloek so .that the despatchers atthe central station where this system.. is i'nstalled, sliould perform the' operations hereinafter described some few seconds before wo minutes'of eleven. The first operations is to more switch 2) so that points 30 and 31 'and and 33 are connected. -By so doing current is caused to flow in the following pathz' positive terminal of battery 20, wires I 60and 148, point 32, .arm .149, point 33, wire 5 6, relay 23, wires 57,- 58. and 59 to the negative' terminal of the battery: The current iiowing in the above traced pathcauses to close contact between wires 27 and-28 as heretofore described and cause the motor 21 to operateand cause the. armature of generator 22'to rotate. A key similar to the individual keys heretofore described, but hav- -ing simply wheels .9 and 10 on a common shaft, is then operated and as wheel v9 has but. one tooth in its periphery, one impulse will be sent to the selectors aty all the diiierentstations to cause the toothed. sectorsl as 102 and 142 to be movedv one tooth so that the tail end' Jthereof as 109 may be moved out of engagement with the pins as 142 on holding pawls 10S so that holding pawls 108 may more into engagement with the sectors as 10T and 143. After the single impulse has been sent, wheel .10 then causes 18 impulses to be sent tothe line of such a polarity that' the vsectors such as 107 and arm 25 and arm 26, so as 143 at all the stations will be advanced 18 steps so that the holding pawl'lOS will rest against the last tooth as and remain in Contact therewith.

The irstenergization of relay 146 causes armature 147 to be raised so that a current tien flowsiin the connects points'30 and '31; positive terminal of battery 20, wires 45, 46 and 151, armature following path as arm 150 147, wire 152, point 30, bar 150, point 31 and wires 153 and 81, relay coil 35 and wires 72, 58 and 59 to the negative .terminal of Ithe battery. Current flowing the above raced path, causes the4 left-ebend end of ist 75 instant Yonly and then immediately opens and is then closed again in one second, andv v:armature 37 to be raised and the arm 33 'to befmoivedr` `,to the right, therebyi causing systemj to ,haye theirleft hand ends simulta- -c ,neouslyffrafised` thereby'- causing the driving soY p awls as 101 of all the selectors oftliesystem to move to the"right,v thereby causing i thersectors as"107to` move so thatpin 111 will contact with spring 112 and move it in contact with spring 11'3 at all the stations. `When the springs 112 and 113 are connected, current can flow from the line wires in the following path; wires 1, 134, 154,

spring 113, spring 112, wire 155, coil 127,

wires 126, 125 and 124, to .line wire 2. As line wires 1 and 2 are connected toboth terminals of the generator 22, the current lowing in the above traced path will cause the` right hand end of armature 130 to be raised, thereby striking a single blow on gong 136. As the-relay armature 147 is raised and allowed to fall by successive energizations and denergizations of relay coil 146, the hammer 135 will announce such fact by a single stroke on gongv136. It will be noticed thatthe bell then operates as a single stroke bell as there is no path for a current ow through coil 139. 1t must therefore be seen v that the' blows given the gong 136 correspond exactly with the single clicks of a telegraph instrument, such yas is now used for announcing time.

As soon as the last blow has been given the gong 136, the operator at the central station depresses the push button 19, thereby causing current to flow in the following path; positive terminal of battery 20, wires 45, 4 6, 47, 48, 49 and 156, contact 160` bridging member 19, contact 161 and wires 162, 69 and 70 through the coil 36 on line relay 34 and by wires 71, 72, 58 and 59 tolthenegative terminal of the battery. The current lowing'in the path traced above, causes the right hand end of armature 37 to be raised, n

ithe armature 38 to be moved to the left and arms 39 and 40 to be moved in contact with i points 44 and 43 respectively, so that current then vflows from the positive terminal of generator 22 to line wire 2, and returns by line wire 1, andpasses through all oi' the selectors at the di'erent stations in such al direction that the right hand end of armature 96is drawn upwardly and as sector 107 is in the moved position and its tail end 116 has been lowered, the driving pawl 100 engages with member 117 and raises the saine so that as soon as the movable member 19 is released and the circuit is broken therethrough and the current ceases to flow to the line, the selector becomes denergized and the arm 117 in returning to normal position by gravity, causes the'release pawl 103 to'engage with the holding pawl 105, 'throw it Vout ,of-v, engagement; oli tl-1e teeth of ".sector ,102 and then Ipalloni.as; SQlfei-,fexkplamechf ot -zthe'partsioraill ,ofA iefstations toneturi lo'thegnormal-pdsiiiion "le securebyv-Letters Patent, :is: n
